    Expansion modules

    Expansion modules developed in Mramor Robert s.p. for Unitronics PLC
  3. JZ- EX 8Di -8Do Dear UNITRONICS users. This is my another device, which i developed, and it's used several times in my projects. This expansion module looks like EX90-DI8-RO8 expansion module from Unitronics. Our module also have 8 digital inputs which can be sink or source configurated, and 8 digital (transistor) outputs which can be also sink, source or even for AC voltage configurated with max. 0,5A current per output. This module can be connected to any OPLC from Unitronic series. The module communicating with PLC via RS485 port. In this case JAZZ series needs a RS232/RS485 Add-on port (JZ-RS24 ) Also PLC must have a short communicating software which is in attachment. It's wery short, occupies only 7 nets. The second choice of this module is standalone mini PLC, because is based on Atmel AMEGA168 AVR with a 16k of programming space. It can be updated up to 128k programming space on request. If you have a skills of AVR programming, there is no problem to write your own software (AVR studio, Arduino, Bascom ) and upload him thru ISP port. The modules can be networked via RS485. Also is possible connect some device like HDD44780 based LCD diplay to ISP port! The power supply for module is 10V to 30VDC or AC, and power consumption is obout 3W. Specification: Board size (WxHxD): 90x77x60 mm - DIN32 module base Digital inputs: 8 inputs in 1 group , pnp or npn (10- 30VDC,AC on request) Digital outputs: 8 digital outputs in 1 group , pnp or npn , max. 0,5A per output – fused (10 -30VDC/ AC) Response time (inputs/outputs): approximately 30ms Communication: RS485, 9600,8,1,N Power supply: 10 – 30VDC/AC , 3W For further information or orders, please write to : biogorilniki@gmail.com The kit contains: Expansion module with preloaded software, module base and connectors User manual Software for communication and test for JAZZ : Komunikacija JAZZ Rev. 2..1_2018.U90 Wiring procedure: JAZZ expansion wiring - source.xps Expansion board and JAZZ uploaded with test program
  4. Dear Joe. The price of this little gem is 30€ Best regards Robert M.
  5. Dear UNITRONICS users. Sometimes it happens that you need more digital inputs on the OPLC because of pushbuttons. A solution is an OPLC with a larger number of inputs or an extension needs to be added when is possible. That can be expensive. I developed a simple solution, which I named, the pushbuttons to current loop converter. In this case, you only need one analog input (4 – 20mA), to add up to 19 pushbuttons via two-wire shielded cable which can be up to 100m long. The converter is self powered ( powered from current loop ). The converter is reliable, since a very stabilized reference circuit is used. The error is maximum +/- 1 digit on 10bit AD I attach software for JAZZ with examples for easier understanding. It can be also used with others OPLC. The converter is only available in our company for now. For further info write on Email biogorilniki@gmail.com. Best regards Robert Mramor s.p. Pushbutton to current loop - debouncing.U90
